AbilityHydroelectric Power
You may make Floodlight do 10 more damage for each Water Energy attached to Lanturn, but not used to pay for Floodlight's Energy cost. This power can't be used if Lanturn is Asleep, Confused, or Paralyzed.

Lanturn is Pokédex #171, generation 2 (Johto). Lanturn is a Stage 1 Lightning Pokémon with 70 HP. The card lists level 26. The card says it evolves from Chinchou. In this catalog that name is Chinchou (#170).
Lanturn sits at 38/111 in Neo Genesis, position 38 of 111. Before it is 37 Granbull, and after it is 39 Ledian. The set belongs to the Neo series. It was released on December 16, 2000. The printed size is 111, and the checklist is the same length. The listed rarity is Uncommon.
Hydroelectric Power is listed as Pokémon Power. You may make Floodlight do 10 more damage for each Water Energy attached to Lanturn, but not used to pay for Floodlight's Energy cost. This power can't be used if Lanturn is Asleep, Confused, or Paralyzed. The attack Floodlight lists 20 damage. The cost is Lightning, Lightning. Flip a coin. If heads, the Defending Pokémon is now Paralyzed. Weakness is Fighting ×2. Retreat cost is 2. The flavor text reads "The light it emits is so bright that it can illuminate the sea's surface from a depth of over three miles."
Lanturn (#171) has 25 other cards in the catalog. Those other cards are in 21 sets. The other printings with a release date run from 2001 to 2024. The earliest other card is Lanturn 32/64 in Neo Revelation (2001). That card lists 80 HP, and this one lists 70 HP. Both list the rarity Uncommon. Kagemaru Himeno illustrated that card, and Ken Sugimori illustrated this one. 25 other cards of Lanturn list a different HP.
The illustrator line reads Ken Sugimori. I count 1,112 other cards in the catalog with that illustrator.
Neo Genesis set binder is where a full Neo Genesis set goes. This card fills one slot there. A generation binder holds one card of each species. Lanturn can fill a slot in Generation 2 binder (Johto). I still need this card.
